Question:
is there a wiring harness that I can tie into the trailer brake controller I already have on my RV?

The Brake Buddy Stealth part # HM39530 can only work with the included brake controller. You'd have to install the controller that comes with this to use it with the Stealth and then use your current controller when towing a trailer.
